固体矿产资源储量评价方法研究现状

矿产资源评价作为一种围绕特定区域内矿产勘查而进行的长期性、系统性和前期性的综合研究。本文综述了我国固体矿产资源储量评价的一般原则和发展历程,重点介绍了在固体矿产资源储量评价中常用的传统几何评价法、地质统计学评价方法、SD评价法等。

基于中国特殊地质特性的页岩气储量评价方法研究

页岩气成藏模式及赋存特点都不同于常规天然气,目前国内已发展比较成熟的常规天然气资源储量预测方法并不能直接适用于页岩气资源储量的预测。文章根据页岩气发育条件及富集机理,结合油气资源评价方法的基本原则,系统归纳了国内外常用页岩气资源潜力定量计算方法,结合中国地质背景的复杂性和页岩气勘探开发程度较低的现状,建议在页岩气开发不同阶段采用不同的储量评价方法。根据国内天然气储量评价经验,文章建议将齐波夫定律引入页岩气储量评价方法体系。

Evaluation model for safety capacity of chemical industrial park based on acceptable regional risk

The paper defines the Safety Capacity of Chemical Industrial Park(SCCIP) from the perspective of acceptable regional risk. For the purpose of exploring the evaluation model for the SCCIP, a method based on quantitative risk assessment was adopted for evaluating transport risk and to confirm reasonable safety transport capacity of chemical industrial park, and then by combining with the safety storage capacity, a SCCIP evaluation model was put forward. The SCCIP was decided by the smaller one between the largest safety storage capacity and the maximum safety transport capacity, or else, the regional risk of the park will exceed the acceptable level.The developed method was applied to a chemical industrial park in Guangdong province to obtain the maximum safety transport capacity and the SCCIP. The results can be realized in the regional risk control of the park effectively.
